Organic light-emitting devices (OLED) are extremely sensitive to moisture and oxygen. Without high-performance hermetic seals, the life of these devices will be limited. A large amount of desiccant has been used in the packaging of OLED to ensure a dry environment. However, for top-emitter OLEDs, particularly for active matrix displays where the OLEDs are directly integrated on top of a thin film transistor (TFT) layer, the light must pass through a transparent encapsulating layer above the OLED, leaving little room to house the desiccant. Thus, a transparent layer with embedded moisture getter, such as zeolite, would be desirable. Here we report an effort to prepare such a transparent composite film containing zeolite nanoparticles, and show that such architecture is indeed possible.
